Block_Err
Possible Reasons
OUT Status
Block Configuration error
SELECT_TYPE = 0 (uninitialized)
BAD + Out Of Service
See Note A
Input Failure/process variable has
BAD status
SELECT_TYPE = AVERAGE and at least one IN is BAD
BAD + non specific
Out-of-Service
The Actual_Mode is OUT OF SERVICE
BAD + Out Of Service
NOTE A
:
The specific block cannot be switched out from OUT OF SERVICE due to the Configuration Error. The Bad-Configuration Error Status
is overridden by the Bad-Out Of Service Status.
OUT Status
When in AUTO mode the OUT reflects the Value and Status of the selected input (IN_x).
If there are no inputs used, or the number of inputs with GOOD status is less than the MIN_GOOD value, the OUT status shall be
BAD-Non Specific.
The SELECTED output shall have Good(NC) status, unless the block is out of service.
With the STATUS_OPTS it is possible selects the following options:
• Use Uncertain as Good
: Set the IS_OUT status to Good when the Selected Input Status is Uncertain
• Uncertain if Manual Mode
: The Status of the IS_OUT is set to Uncertain when the Mode is set to Manual

The RESOURCE BLOCK is not in AUTO mode
Set the Target Mode of the RESOURCE BLOCK to AUTO
mode
The Block is not scheduled
Design the FB Application correctly and download it to the
